There are some types of bacteria that produce toxins which can disrupt the normal functioning of the nervous system. These toxins are called neurotoxins. Tetanus and botulism are two of the common diseases caused by these kinds of toxins. Tetanus is caused by a bacteria called Clostridium tetani. The toxins produced by these bacteria trigger too many nerve impulses that can lead to muscles spasms. The muscles are not able to relax because of this. A certain antitoxin is needed to neutralize the toxins. Tetanus can be lead to death due to spams of the respiratory muscles.
Botulism is a certain type of food poisoning caused by Clostridium botulinum. This is characterized by typical symptoms of food poisoning such as diarrhea and vomiting. The toxins of these bacteria inhibits the release of acetycholine, a chemical that is essential for muscle contraction. Thus, without acetycholine, the muscle fibers are not able to relax.

During the first phase, the affected person might experience blurred vision and difficulty in speaking or swallowing. The treatment must be given immediately because this disease can lead to death. A specific antitoxin should be administered right away.
